Hey all my 410XL currently stop working, Any insight would be great. My current set up is a Hartke LH1000 amp head powering a Hartke 4x10XL (400watts 8ohms) and a Fender Bassman 1x15 (250watts 8ohms). I have always used it in dual parallel mode (2 x 320 watts at 4ohms) and its been great, using the balance nob to give the 410 a bit more volume than the 115. We are doing some recording this weekend where I only need the 4x10 and the manual states if you are only using one cab (my one 4x10) you must use a speakon cable and switch the button to bridged mode. I went to Guitar Center and they sold me a LIVE WIRE ELITE SPEAKER cable after giving them all this info. I came home and switched the button to BRIDGED mode and connected my LH1000 to my 4x10 and had no sound until I turned the volume to 2 and had a loud pop and then no sound at all. After that I reconnected everything like i had it before in dual parallel mode and my 1x15 worked but my Hartke 4x10 made no noise at all. Did they sell me the wrong cable? How did my 4x10 cab stop working? Thanks for any help!
